SANTA ANA, California — A man convicted of killing the father and sister of his ex-girlfriend in a fiery attack on the family's Southern California home has been sentenced to death.

The Orange County district attorney's office says 30-year-old Iftekhar Murtaza was sentenced Tuesday in Santa Ana.

He was convicted for the murders of 56-year-old Jay Dhanak and his 20-year-old daughter Karishma in 2007.

Prosecutors say he killed the pair in a plot to reunite with his then-18-year-old ex-girlfriend Shayona Dhanak after she ended their relationship citing her Hindu family's opposition to her dating a Muslim.

Authorities say Murtaza and a friend burned the family's Anaheim Hills home and kidnapped and killed Dhanak's father and sister, leaving their bodies in a park.
